BACKGROUND: Carotid-femoral pulse wave velocity in hemodialysis patients is influenced by multiple factors.OBJECTIVE: To explore the carotid-femoral pulse wave velocity (PWVcf) changes and related factors in maintenance hemodialysis (MHD) patients.DESIGN, TIME AND SETTING: Non-randomized control experiment was performed at the Third Hospital of Peking University from January to August 2006.PARTICIPANTS: A total of 66 MHD patients were selected from Third Hospital of Peking University.METHODS: General clinical conditions, biochemical indexes, PWVcf and subjective nutritional state were evaluated. MHD patients were divided into two groups according to the state of nutrition evaluated with SGA: non-malnutrition (n=49), malnutrition group (n=17). The PWVcf of two groups was compared, and one-way and multiple regression analyses were performed to explore PWVcf-relatest factors.MAIN OUTCOME MEASURES: PWVcf, blood albumin and parathyroid hormone.RESULTS: PWVcf was significantly positively correlated with age (r= 0.284, P< 0.05), systolic blood pressure (r= 0.468, P<0. 001), and pulse pressure (r=0.451, P< 0.001), while negatively correlated with prealbumin (r=0.318, P< 0. 05),plasma-albumin (r=0.263, P< 0.05), parathyroid hormone (r=0.167, P< 0.05), serum creatinine (r=0.347, P= 0.004)and transferring (r=0.284, P < 0.05) before dialysis. Multiple regression analysis demonstrated that pulse pressure and parathyroid hormone were independently related with PWVcf. The PWVcf was significantly increased in malnutrition group compared with non-malnutrition group (P < 0.05). CONCLUSION: Pulse pressure is the major clinical determinants of arterial stiffness in patients with MHD independent of conventional risk factors for cardiovascular disease; Malnutrition and atherosclerosis are common complications of MHD,showing close relationship. The PWVcf was significantly increased in malnutrition patients.

Objective To observe the efficacy and safety of recombinant human interleukin-11 (rnIL-11) in the treatment of thrombocytopenia induced by chemoradiotherapy in patients with solid tumor.Methods Solid tumor patients whose PLT count was lower than 50 × 109/L from December 2010 to December 2012 in PLA general hospital of Chengdu Commond were studied.They were divided into two groups randomly.The observed group was given subcutaneous injection of recombinant human interleukin-11 (Ⅰ) at the dose of 25 g · kg-1 · d-1,until the PLT rising subsolute value was more than 50 × 109/L.The control group was given usual treatment.The vital signs,hepatorenal function,coagulation function and cardio-pulmonary function of the patients were recorded during the whole process of treatment.Results The patients after chemotherapy had the platelet lowest average of (27.4 ± 7.6) × 109/L,and the average of the control group was (28.1 ± 7.9) × 109/L.The difference was not statistically significant (t =1.083,P ＞ 0.05),but treatment after the observation of elevated had the platelet highest average of (116.3 ± 22.8) × 109/L,which was significantly higher than that of (76.2 ± 21.3) × 109/L; the difference was significant (t =21.092,P ＜ 0.05).Platelets of patients in the observation group were ＜50 × 109/L for several days with an average of (4.3 ± 1.7) d,while platelets rose from the lowest value of the average absolute value greater than 50 000 hours (6.8 ± 2.4) d,shorter than the control group.By comparing the two groups,the differences were significant (t =11.347,P ＜ 0.05 ; t =15.196,P ＜ 0.05).Two groups of patients can tolerate adverse reactions.Ⅲ,Ⅳ degree of adverse reaction was not observed.Conclusion This study shows that rhIL-11 is well tolerated and has thrombopoietic activity in the treatment of thrombocytopenia.

AIM: To investigate the clinical effect of panretinal laser photocoagulation combined with calcium hydroxide in the treatment of diabetic retinopathy(DR).

METHODS: Selected 120 cases(204 eyes)of DR patients who were treated in our hospital from January 2014 to December 2015 were randomly divided into study group(116 eyes in 66 patients)with calcium hydroxide, control group(88 eyes in 54 patients). Two groups were treated with panretinal laser photocoagulation, and the clinical effect of the two groups were compared.

RESULTS: At 6mo after surgery, BCVA of study group was higher than that of control group, the difference was statistically significant(P<0.05); at 3 and 6mo after operation, fluorescein leakage area of the study group were lower than that of control group, the difference was statistically significant(P< 0.05); at 3 and 6mo after surgery, central macular thickness(CMT)of the study group was lower than that of control group, the difference was statistically significant(P<0.05); the study group had complications after surgery in 4 eyes(3.4%)and 5 eyes(5.7%)in control group, the difference was not statistically significant(P>0.05).

CONCLUSION: Compared with simple laser photocoagulation, panretinal laser photocoagulation combined with calcium hydroxide for III - IV stage DR reduce fluorescein leakage area and CMT.

OBJECTIVETo explore the effects of rearing patterns on diet and temperament traits among infants in urban areas.

METHODSA total of 480 25-30-month-old infants were randomly selected from the birth cohort in Hefei Maternal and Child Health Care Center in 2008. A household survey was conducted using China Toddler Temperament Scale (CTTS), Dietary Characteristics Questionnaire and Family Environment Questionnaire.

RESULTSOf the 430 surveyed households, there were three main rearing patterns including parents rearing pattern (Group A), grandparents rearing pattern (Group B) and joint rearing pattern (Group C), accounting for 33.0%, 21.2% and 45.8%, respectively. Infants in Group A tended to adopt processed food pattern, with poor rhythmicity and adaptability; infants in Group B tended to adopt fruit, vegetable, and cereals-based food pattern, with relatively poor rhythmicity; infants in Group C tended to adopt aquatic products and fruit/vegetable-based food pattern, with good rhythmicity and adaptability. Linear regression model showed that infants who consumed more aquatic products, high-protein food, and fruits/vegetables had more positive temperamental traits, whereas infants who consumed more processed foods had more negative temperamental traits.

CONCLUSIONSA joint rearing pattern may be a favorable rearing style for infants aged 25-30 months in urban areas in terms of diet and temperament traits.

OBJECTIVETo evaluate the impacts of maternal weight gain during pregnancy on offspring weight and obesity from birth to 24 months of age.

METHODSThe information on maternal pre-pregnancy body mass index (BMI), gestational weight gain and demographic characteristics were collected from 317 pregnant women. The information on offspring weight, BMI and breastfeeding data was obtained from various follow-up examinations from 0 to 24 months of age.

RESULTSThe logistic regression analysis showed that excessive gestational weight gain resulted in an increased risk of obesity in children at age of 6 months (adjusted RR=3.56, 95% CI:1.31-8.35) and 9 months (adjusted RR=2.87, 95% CI: 1.04-3.28) after adjustment for potential confounding factors. The linear regression model showed that there were significant correlations between gestational weight gain and Z score of weight in offsprings at birth (β=0.032, 95% CI: 0.008-0.057), 3 months (β=0.037, 95% CI: 0.013-0.062), 6 months (β=0.043, 95% CI: 0.017-0.068), 9 months (β=0.038, 95% CI: 0.013-0.063) and 12 months (β=0.034, 95% CI: 0.009-0.059), but not at 18 months and 24 months.

CONCLUSIONSExcessive gestational weight gain may affect offspring weight and increase the risk of obesity in children from birth to 12 months of age. During their second year of life, this effect will temporarily disappear.

OBJECTIVETo explore the effect of clinical application of stand-alone MC+PEEK cage in anterior cervical fusion.

METHODSFrom January 2011 to January 2014,50 patients were treated with the MC+PEEK cage filled with autogenous cancellous illic-bone graft after anterior cervical discectomy. There were 22 patients with cervical spondylosis,26 patients with traumatic cervical disc herniation, 2 patients with cervical instability in these patients. There were 32 males and 18 females, aged from 30 to 79 years old with an average of 53.30 years old. There were 32 patients with single segment, 15 patients with double segments and 3 patients with three segments. Cervical AP and lateral and the flexion-extension X-rays were regularly taken in order to assess the cervical physiological curvature, the graft fusion and internal fixation related complications. Nerve function, clinical effect and bone fusion were respectively evaluated according to Japan Orthopedic Association (JOA), Otani grade and Suk method.

RESULTSAll patients were followed up from 6 to 36 months with an average of 20 months. No correlated surgical complications were found and all patients obtained bony fusion with an average time of 4.30 months. JOA score had significantly improvement after surgery (P < 0.05). The JOA score was 10.60 ± 3.00 before surgery and 16.10 ± 2.20, 16.40 ± 2.35 at one week and six months after surgery respectively. According to Otani grade,40 cases got excellent results, 9 good, 1 fair. No significant dysphagia and internal fixation related complications such as displacement of cages were found during the follow-up period.

CONCLUSIONUsing this cage in anterior cervical fusion can obtain satisfactory clinical effect with less operation injury and reduce the complications. It is a better fusion method in anterior cervical fusion.
